What's the opposite of scaffolding a lesson? It would be saying to students something like, "Read this nine-page science article, write a detailed essay on the topic it explores, and turn it in by Wednesday." Yikes -- no safety net, no parachute, no scaffolding -- just left blowing in the wind.
This article was a reading assignment for the Science Teaching Methods course I'm also currently taking, and I thought that it had wonderful connections to Constructivist learning and the inquiry model, so I thought I would share. It has some good information and insight all the way to the end!
